Magic Trapping of a Three-Level System for Rydberg Quantum Computation

For over a decade, enormous e ort has been invested towards building a practical quantum computer. Such a machine promises to revolutionize scienti c computing, but there are many challenges to be overcome. The dominant problem for most proposals is decoherence: random and uncontrollable loss of quantum information to the computer's environment. Here we consider one promising implementation for quantum computation using the Rydberg blockade mechanism, which stores qubits in optically trapped neutral atoms. A detailed theory for these optical traps is presented. While the traps are essential, they induce decoherence in the atoms they trap. We propose a method of "magic" trapping by which this decoherence may be completely removed. Numerical calculations show that, while the commonly used alkalis cannot be trapped with this scheme, a "magic" trap could be built for aluminum.
